Upon opening the app users will apparently be required to input a Microsoft account before Cortana - named after a character from the Halo game series - seeks to discover more about its owner.

Users will be asked to choose a nickname, input data about how they like to spend their evenings, what their food preferences are, as well as favourite activities and topics they'd like to stay updated on.

If you Build it...

Once the set up is completed, Cortana will ask users how it can be of assistance, giving Windows Phone fans the opportunity to ask questions, request playlists, set alarms and more.

It seems the app will be accessed from a Start screen Live Tile, but will also be availably by pressing the soft Bing search key beneath the touchscreen.

That's enough from us, though, you can take a peek at Cortana yourself in the video below, although we're sorry to say her voice hasn't been revealed just yet.
